1. Preamble
The strategic management is gaining a lot of importance nowadays. A lot of
companies are facing the issue that they have several products and even several
strategic business units. To achieve competitive advantages in the market, the top
management has to decide how to split up resources between these units
regarding several factors to get a well-balanced and a future-proof portfolio.
Furthermore potentials for failure as well as for success have to be identified to
stay competitive. An important tool for the strategic management is the portfolio
analyses which has the goal to improve the planning. Based upon the outcome of
this tool decisions should be made on future activities. There are two well-known
portfolio analyses established that will be presented in this paper, the Boston
Consulting-matrix and the McKinsey-matrix. They will also get compared to see
when to use the one and when to use the other and to analyze their advantages
and disadvantages.

2. Portfolio analysis
The most portfolio analyses have in common that they display the business
environment and the potential of a company on a two-dimensional
representation. They differ in the overall target of the whole portfolio analysis and
in the manner, the internal and the strength of the environment is measured. In
general, it is possible to divide all portfolio analyses into two groups. The market-
oriented portfolios and the resource-orientated ones. The resource-orientated
portfolios try to give recommendations about the usage and change of resources
based on their conditions and the market. The two most known resource-
orientated portfolios are the technology portfolio and thee business area-
resources portfolio.
The BCG-matrix and the McKinsey-matrix are both market oriented portfolios. The
main goal of the market-oriented portfolios is answering the question which
products or strategic business units need more financial attention and which units
could offer this attention. Consequently this leads to considerations on the
creations of a financially balanced equilibrium. (Bea und Haas 2016, S.150)
3. The BCG-matrix
The BCG-matrix was developed by the Boston Consulting Group in the late 1960's
and the early 1970's. The well-known company had to deal with the Mead Paper
Corporation, which had 45 operating divisions and 6 product lines by this time.
They hired the Boston Consulting Group to manage the different business units
and to define which product groups or business units were losing money. By doing
that, they wanted to be able to create an overall company strategy and
furthermore the top management wanted to know how to allocate or reallocate
resources between the different business units. Since this time, this portfolio
4
analysis is probably the most important tools for strategy setting and is used by a
lot of companies and taught by a lot of professors and books. (Paul und Wollny
2011, S. 208)

3.1 Description of the BCG-matric

To meet all requirements of their customers, the consultants built up a framework
which consisted of four categories. They tried to put every product line and every
strategic business unit into one of these categories and deduce recommendations
for the future strategic direction of each entity. In practice they consulted, if in
particular, units should be invested or disinvested, should be acquired or sold or
liquidated.
The ordinate of the four-cell matrix describes the environmental dimension by
considering the market growth. The abscissa demonstrates the relative market
share. (Kessler 2013)
It is important to mention, that the portfolio approach is based upon the product
lifecycle and the experience curve in its whole consideration. The usage of the
dimension of the market growth is highly linked to the product lifecycle. Based on
the product lifecycle, it can be assumed that markets undergo four phases which
lead to suggestions about the market growth and the market attractivity.
The concept of the experience curve claims that with every duplication of the
accumulated output quantity the real unit costs could potentially decrease by 20-
30 percent. This means that the company with the highest market share is able to
provide the lowest unit costs. (Paul und Wollny 2011, S. 209)
The relative market share is measured by the ratio between the own absolute
market share and the absolute market share of the biggest competitor. This means
the factor is a doubled relative value, which is smaller than one when competitive
situation is strong and the company is the market leader. And higher than one
when the competitive situation is low and the company is the market leader.
6
Furthermore, if the value is exactly one, the market share is exactly the same like
the one of the most important competitor. Sometimes the area between one and
one and a half is highlighted. This is based on experiences by the Boston Consulting
Group which says that the cost advantages first starts to become increasingly
important when the market share of a company is 50 percent higher than the one
of the biggest competitor.
The market growth rate is the result of the development potential of the market in
the coming years measured in percent. "It is generally considered that a growing
market experiences an increase of around five percent of its sales by volume." This
means that the market growth is usually quantified by the increasing respectively
decreasing turnover measured in a predetermined period, usually one year, in a
specific market. (Pepels 2015, S. 84–85)
So, the abscissa and the ordinate define a field which is divided into two sections
which leads to four categories as it can be seen in Image 1. Each strategic business
unit or each product gets now evaluated and entered in the matrix, presented by a
circle. The size of the circle corresponds to the proportion of the relative turnover
created by this product or business unit related to the overall turnover of the
company.
The peculiarity of the matrix is that wherever the to be evaluated product gets
positioned, the company is able to derive a standard strategy or an advise how to
handle this product in the future.
To exemplify the situation which the products or business units find themselves in,
the Boston Consulting Group gave the four categories descriptive names:
The Poor Dogs describe the quadrant of a low market share as well as a low
market growth. Those are usually problem or discontinued products, that find
7
themselves in the degeneration respectively saturation phase. The issue is that
they may block resources that could be used in other areas much more efficiently.
There are two given possibilities to handle these markets. To minimize the risk of
this area and to relocate the resources, it is suggested to disinvest or to stop the
product completely. The other opportunity is to relaunch a variation of the
product by concentric, horizontal or lateral diversification. But therefore, it has to
be proven that there is a realistic chance to survive for this relaunched product.
Summed up, the development costs, the investments in capacities and the
marketing and sales costs are low or zero. The main advised strategy is to stepwise
pull selectively out of the productline if it is not able to provide an appreciable
contribution margin or the resources could be used better elsewhere.
The Question Marks are characterized by high market growth and a low relative
market share. Those are new businesses or successor products that are still in a
very early stage of the product life cycle. Their name Question Marks concludes
that it is uncertain whether they're able to survive and develop in the market and
if it is wise to invest or not. This leads to a selective strategy where it is suggested
to analyze in detail in to which of them further financial resources for developing,
sales and marketing and capacities should flow, as they are promising success or
which of them should be rejected. This is also important as it is usually not possible
for companies to finance all upcoming projects.
If it is decided to develop the business there are high initial costs combined with
still pretty low market shares which leads to a negative cash flow in the beginning.
To be able to increase the market share, it has to be driven an offensive and risky
strategy. This means a high investment in improving the value propositions,
8
specialization of the product, implementation of the technical innovations and an
expansion in the sales policy.
As the risks and the consumption of resources are high, a company is able to only
have a limited number of these businesses in their portfolio. On the other hand, it
is crucial to invest in these markets to stay long-term competitive.
All in all it has to be decided in each particular case whether it is worth it to push
business further or to disinvest and to relocate resources. (Reisinger et al. 2013, S.
95f.)
The Stars have both, a strong relative market share and a high growth rate. This
means on the one hand that they're generating a lot of money but on the other
hand that they need high investments to cope with the high market growth rate
and to support the market dominance. Typically, these products would find
themselves in the period of growth in the product life cycle. In this area the
strategic management is advised to invest in developing, marketing and sales to
maintain its large market share and to become a cash cow when market growth
rate goes down. The risks in this category should be accepted. Therefore, more
effort should be put in the product or the strategic business unit by diversifying,
widening the customer range, opening new markets and improving and supporting
the sales situation. This means it has to planned with continuously reinvestments.
Once the market comes to its saturation phase the endurance and the investments
to keep the high market share pay off and the product is ready to become a cash
cow. Every diversified business portfolio should have some star products in their
backhand to ensure future cash flows and monetary resources that can be
reinvested.
9
The Cash Cows are identified by a high relative market share but a low market
growth. In this area the return on assets is greater than the market growth rate
and thus achieve a higher outcome of money than they consume as it is absolutely
unattractive for competitors to enter the market due to the high market shares.
Moreover, the high market share leads, based on the theory of the experience
curve to a greater potential in cost and efficiency optimization. It is generally
advised to either not reinvest at all in these areas and to "milk" or "harvest" these
products or to invest just very slightly to defend the market share as long as
possible. Another opportunity is to reanimate the business by product variation to
turn it again into a Question Mark or a Star. But this is the exceptional case and has
to be weighed up very carefully.
Usually the Cash Cows are used as capital providers to turn Question Marks into
Stars, to cover administrative costs of the company and fund the research and
development departments and the less lucrative units. As they are this important
for the whole survival of the company, it is well-considered to have the half of the
overall business portfolio as Cash Cows. (Paul und Wollny 2011)
3.2 Criticism of the BCG-matrix
As this strategic tool is very popular and in addition quite old as well, it has to face
of course some points of criticism. To start with, the matrix only differentiates
between "high" and "low", the user could be lead to an untrue black-and-white
mindset. Furthermore, critics claim, that the scaling was set randomly and the
10
companies should scale their BCG matrix especially for themselves, which is once
again very difficult and problematic.
Another point is that the labeling of the boxes are judgmental. This brings in an
emotional component and people employed in a "poor dog" SBU could be
discredited. (Drews 2008, S. 43)
As the portfolio analysis tries to combine the environmental analysis and the
internal situation, it is a highly important tool for the strategic planning. A big
disadvantage is that the BCG-matrix only uses one characteristic for the
environmental situation and one characteristic for the situation in the own
company. (Bea und Haas 2016)
The chart uses the relative market shares as an indicator for competitive strength.
This is mainly founded in the PIMS study, which shows a direct dependence of the
relative market shares and the return on investment. As the origin of the study lies
in the early 1960's, there were a lot of other studies in the meantime which were
able to refute or at least challenge this old concept. Furthermore, it is obvious,
that if the evaluation of the competitive strength only happens through the
relative market shares, like it does in the BCG-matrix, companies that drive a cost
leadership strategy, get rated much better and companies that drive for example a
differentiation or a niche strategy get rated worse. Another important negative
11
point in concentrating only in relative market shares is the problem in determining
in the exact market and your own shares in it. The same issue faces the market
growth on the x-axis of course as well. (Drews 2008, S. 43)
Probably the most important critic of the whole concept is the point that the
market attractivity can't be really measured only by the market growth as there
exist markets that don't grow and are attractive for companies.
Another big problem for both axis of the framework is the definition of the market
and its demarcation, as the borders are blurry and fluent and often hard to define.
(Paul und Wollny 2011, S. 213)
12
The McKinsey-matrix
As the BCG-matrix had to meet a lot of criticism for the just given reasons, there
was developed another strategic planning tool: the McKinsey-matrix. In the late
sixties and early seventies General Electric, a multinational conglomerate
operating in a lot of segments like aviation, healthcare, power, renewable energy,
manufacturing, finance, transporting and so on was seeking for a tool to
differentiate the potential for future profit in their many business units. The
company was disappointed in the return on investments they had in their various
businesses which suggested faults in GE’s approach to investment decision-
making. The strategic top management of General Electric came to the conclusion
that the BCG-matrix with only one indicator for the external situation and one
indicator for the internal situation isn't eligible for their portfolio approach.
That's why they went to McKinsey and Company, another well-known american
consultancy, to get advised within their portfolio and investment strategy. The
company designed an approach for GE that differs in two ways from the BCG-
matrix. As it can be seen in Image 2, it has nine instead of four blocks and the axis
describe the internal and external situation completely differently, using market
attractiveness and competitive strength. The matrix is also known as GE-matrix or
nine-box matrix.

Image 2: The McKinsey-matrix
4.1 Description of the McKinsey-matrix
To meet all requirements, the consultants developed a screen and tried to include
some more sub-indicators in the two main indicators. Therefore, the compounded
values are based on a scoring model to insure a better coverage of both
dimensions and also to be able to include qualitative aspects in the portfolio.
Based on the positioning in the portfolio the user is able to apply standard
14
strategies and recommendations to ensure a well-balanced and a future-proof
business portfolio.
The ordinate of the nine-cell matrix describes the environmental dimension by
considering the market attractiveness which includes different criteria. The
abscissa is handling the internal company dimension by regarding the competitive
strength which as well includes different factors and criteria. The two axis create a
nine-cell matrix as they are subdivided by high, middle and low. (Grünig und Kühn
2018)
After it is defined which factors should be included, the determination is made by
scoring points. Each criterion is evaluated individually and included in the overall
rating. From this, the average is formed, which defines the position within the
scale of abscissa and ordinate.
Just like in the BCG-matrix, the size of the circles of the to be evaluated product or
business unit corresponds to the turnover related to the overall turnover of the
company. Furthermore, depending on the position of individual units, it should as
well offer guidelines for strategic behavior. The overall goal of these
recommendations is the maximizing of the return on investment. (Bea und Haas
2016)
This portfolio analysis is able to respond each company's needs as it is able to
include different sub-factors in its axis which generates one main factor. To define
how for example the market attractivity has to be defined, it has to be chosen
which factors should be included. These factors can be weighted and rated
differently in the framework of a scoring model. (Pepels 2015, S. 96) The rating is
influenced by quantitative data (for example the turnover in figures), the
description of quantitative data (for example market leader based on turnover)
and by qualitative aspects (for example the degree of the competition). (Paul und
Wollny 2011, S. 220)
15
To determine the market attractiveness and the relative competitive strength it is
important to understand that there is no predefined list of factors that has to be
included. In each case it has to be differentiated and considered which factors are
crucial.
To give an overview of the given possibilities to describe the market attractiveness
the literature suggests a catalog of four main factors that could be involved. The
first one is the market size respectively market growth by analyzing for example
the market volume, the historical market growth, the development of the market,
the stage in the market life cycle, the impact of productivity increase and the
expansion of the market space.
The next main criteria the market quality is evaluated by the return on sales, the
technical know-how which is given in the company and the ability to protect it, the
intensity of the competition and the number of competitors, the strengths of the
market entry barriers, the level of needed investments, the potential of
innovations, seasonal fluctuation, requirements of distribution and service
performance and the financial scope of price setting.
The third main factor considers the needed resources and the energy supply.
Those are affected by the power and the reliability of the suppliers, the given
alternatives of suppliers and the price stability of the supplied goods.
Last but not least the environmental situation is influenced by the dependency on
economic trends, the market acceptance and restrictions due to political laws and
economies. (Pepels 2015)
On the other side the competitive strength is as well determined by four main
factors, where a big focus is in the area of the value chain. As it will turn out that
the quantification of the selected aspects of the competitive strength is very hard
to do, it is easier to fall back on qualitative elements. Of course, it also depends on
the availability of the needed figures in the market. For rating the following
16
factors, it turned out that the sales manager are often able to give qualified and
good assessments.
The first variable is the own market position which can be characterized by the
relative market share, the financial strength, advantages in pricing or qualities, the
profitability measured in gross profit or EBIT-returns and the growth rate of the
company compared to competitors.
The second ingredient is the production potential, expressed through productivity,
locational advantages, economies of scale and scope, capacity, intellectual
property, technical know-how and flexibility and licenses.
Furthermore, the potential of the research and development should be
considered. This is done by looking at the personal and financial resources and
possibilities and the overall degree of innovation that can be split up in different
factors.
Finally, the qualification and ability of the top management should also be
included. This can be done by evaluating the professionalism, the working
atmosphere and the company's organization. (Paul und Wollny 2011, S. 225)
As with the Boston Consulting Group approach, they should not be applied as
planned strategies without further reflection but should be critically reviewed as
guidelines. (Grünig und Kühn 2018, S. 128)
As the ordinate and the abscissa are divided into high, middle and low, there are
nine areas arising which can be summarized in three zones that determine the
three main norm strategies. These zones are usually colored green, yellow and red.
Besides that, it is also possible to derive more differentiated and specialized
strategies from the single boxes.
The three cells at the top right-hand side of the matrix are the most attractive in
which to operate. It is the zone of investment and growth and they contribute to
the future profits. The main objective in this area is the assurance and the
development of potentials for success, as the high market attractiveness and the
17
relative competitive strength can suggest. Sub-goals are the increase of the
awareness level, the acquisition of companies that are related to the own business
and a high price level. Measures are for example the acceptance of risks, the
optimization of marketing, the increase of the market share and product variety,
the empowering of the market barriers and the opening of new markets.
Therefore, it has to be invested a lot of resources and the consumption of financial
resources is typically greater than the profit. Nevertheless the risks should be
taken as these strategic business units or products are the future profit savers.
(Reisinger et al. 2013, S. 96)
The three boxes at the bottom left-hand side have the least market attractiveness
and the least competitive strength, therefore the top management is advised to
follow a policy of harvesting and divestment unless the relative strength can be
improved. The zone is often colored red. Depending position in the
portfolio and the expected chances of success it is either recommended to
completely disinvest and to even sell or reduce commercial units if the market
attractiveness as well as the competitive strength is low. The other two cells are
characterized by specialization, the exploration of niche markets and an
alternative consolidation or the harvesting of gainings, the minimization of
investments and the planning of a strategic retreat of the product or the strategic
business unit. Summing up, the products in this zone are marked by the release
and the allocation of funds and resources. (Pepels 2015, S. 97)
The three cells running diagonally from bottom right to the top left corner
represent the yellow zone. They either have a low market attractiveness combined
with a high competitive strength, a medium attractiveness combined with a
medium strength or a high attractiveness combined with a low competitive
strength. Depending on the position and the portfolio's balance, it is advised to
defense, to consolidate or to expand. The management of businesses within this
category should be more cautious and with a greater emphasis being placed on
selective investment and earning retention.
18
That's why it is called the zone of selective strategies. The main goals in this area
are the promotion of customer loyalty, the customer acquisition and the rely on
conservative financing options. Actions in this area could comprise a growth
strategy, a high market attractiveness and a low competition, which is reached by
specialization, the provision of a niche policy and the assessment of possible
acquisitions. A middle attractiveness as well as a middle competition result in a
very selective strategy which is conducted by identifying possible expansion fields,
specialization and selective investments. A low market attractiveness and a high
competitiveness lead to a keep-and-safe strategy, where it is advised to maximize
the return of the cash-flow and to invest
only to maintain the product or the strategic business unit. (Paul und Wollny 2011,
S. 219)
4.2 Criticism of the McKinsey-matrix
Now the McKinsey-matrix, like the BCG-matrix and all generic strategy models has
its own set of limitations and points of criticism. The literature often denounces
that the GE-matrix assumes that there is a causal connection between the included
factors and the chances of success of a strategic business unit or a product. This
connection is often different and can only be suggested. This leads to a
degradation of the importance of the derived norm strategies and therefore for
the whole tool.
Another point is that the portfolio only looks at the current situation and ignores
mostly how positions might change through changes in the industry and the
economy.
Furthermore, a big problem is that the qualitative circumstances have to be
evaluated in a subjective process. But decisions are often characterized through
complex structures, unknown interdependencies and unawarenesss of facts. In
19
addition, the selection of the included factors and their weighting is facing the
same issue. The accumulation of these subjective assessments leads to the point
that a previous average of this analysis, the involvement of multiple factors can
lead to a big disadvantage. (Macharzina und Wolf 2010, S. 367–368)
Moreover, it is obviously that availability and the topicality of the needed data is
presenting a complication. This is also related to the difficulty and the costs that
this portfolio analysis requires.
Finally, the McKinsey-matrix is facing of course the same problems as all portfolio
analysis does which are already described in section 3.2. This includes for example
that the result of this tool is sensitive to the definition of business markets. (Paul
und Wollny 2011, S. 230)
5. Comparison of both portfolio analyses
The GE-matrix and the Boston Consulting Matrix are in a lot of points similar.
Nevertheless, both analyses have their right to exist as both of them have different
advantages and operating fields.
To begin with, the biggest difference and the biggest criteria, which should be used
is based on the product the business unit is producing. It should be strictly
differentiated between typical consumer goods which traditionally have a product
lifecycle and products that don’t have a product lifecycle, which are typically found
20
in technical markets. Due to the strong connection between the market growth
axis of the BCG-matrix and the product lifecycle, this portfolio analysis should be
used for products or business units in consumer and anonymous markets that
experience a product lifecycle. On the other hand the McKinsey matrix is useful for
technical and known markets That is the reason why in technical sales for example
the McKinsey-matrix is used as it can’t be expected that the to-be-analyzed
product has a product lifecycle.
Then it should be clarified the difference of the usage of both models. Whereas
the BCG-matrix is mainly used by companies that want to know how to relocate
and how to deploy their resources among their various business units and
products, the GE-matrix is mainly applied to find out how to prioritize investments
among strategic business units.
So first of all, it should be determined, what exactly the intention of the analysis
should be. Then there are different advantages and disadvantages that should be
taken into account. To begin with, the determination of positions in the BCG-
model is a lot easier as it uses clear and quantitative criteria. This is on the one
hand a big plus as it simplifies the whole process. On the other hand, like
previously described in section 3.2, the market attractiveness is way too complex
to describe it only through the relative market growth. On the other side the
involvement of different factors for the measuring of the market attractiveness
and the competitive strength creates a much more realistic presentation of the
external and internal business situation. The interrelation between quantitative
and qualitative data, personal experiences and assumptions of the management
21
and consensus decisions is probably always closer to the reality than only
considering one factor like the BCG consultants do.
Moreover, the classification in to three categories per axis within the McKinsey-
model leads to more differentiated norm strategies compared to the 4 boxes of
the BCG-portfolio.
The BCG-matrix uses the clear correlation between its two dimensions and the
output and use of funds. Therefore, it is much more appropriate to check how
balanced the business portfolio of a company is.
Finally, it can't be said whether the one or the other analysis is better in general.
Both of them have advantages and disadvantages and depending on the needed
complexity, usage and other factors, it should be decided which tool will be used.
(Pepels 2015, S. 99)
22
6. Conclusion
Both models represent an important tool for the strategic orientation of a
company. They enable managers to assess whether the business portfolio is well-
balanced to ensure a long-term profit and survival and growth of the company.
The models shouldn't be seen as tools that require strict observance regarding the
norm strategies nor they answer all strategic questions when it comes to a
diversified business and organization as it was announced when they were
developed in the 1960's and the 1970's.
Instead, the two models should help the management to check the overall
situation of the portfolio and to give cautious estimations about future strategy
changes and improvements. Furthermore, the matrices can be seen as
communication- and moderation tools that represent important milestones in
strategy setting that illustrates a company’s situation. This way, the analyses are
able to overcome a lot of their points of criticism. Both models have several times
been updated, renewed, combined with others and supposed to be replaced. The
reason why they are still very popular and thought quite often, is that both models
represent usual market practices. That's why everybody at least should heard and
understood once those concepts as they generate and create a general
understanding of strategy setting and portfolio analysis.
